11 Ways to Get Prettier, Healthier Skin in Just 1 Week

"Hydrating the skin is crucial, [which includes] drinking the recommended amount of water a day. Just as important is making sure our skin is hydrated by using things such as hydrating masks," said Dr. Debra Jaliman.

After cleansing and toning, always apply a moisturizer. You can even take this a few steps further by applying a preserum, following with a serum or oil, followed by a heavier cream. Overnight hydrating masks can also do wonders for your skin. Try Glossier Moisturizing Moon Mask ($22), which combines sweet almond oil, squalane, and hyaluronic acid. By moisturizing consistently, you'll see a difference in as little as a day.
